Hi all,

Reading a book i have found the next:

"Unfortunately, there has to be a throttling in a valve in the UC leg, which takes the larger part of the flow."

This part is talking about pressure drop and, because of my bad english, i donīt understand what "throttling in a valve" means. The translation of throttling in spanish has no sense at all.

Can anybody explain it to me in another words?

Regards
